After several years of low price competition and industry integration, LED lighting industry has entered a mature stage. Product cost-effective significantly improve the application of market penetration, the traditional application market gradually saturated. The competitive power of enterprises is shifting from enterprise scale and product cost to product and technology ability gradually, and the added value of products is becoming more and more obvious.

The rise of the internet of things leads to the high value digital illumination of the LED illumination toward the small network. The intelligent system can collect users, environment and other information through various sensors, and analyze the data, then adjust the equipment. Integration of personalized, people-oriented intelligent lighting is becoming the focus of future industrial development.

2017, with the development of technology, product maturity, manufacturers actively promote the concept of intelligent lighting, the global intelligent lighting market into a high-speed development phase, the market size of nearly 4.6 billion U.S. dollars, the annual growth rate reached 95%. It is expected that the market will continue to grow in the next few years, and the global intelligent illumination will reach US $13.4 billion by 2020.

Intelligent lighting as a smart city access with the innate advantages of major manufacturers active layout

Intelligent lighting can not only achieve higher profit margins, but also the smart city's excellent access point. With the continuous development of cities, energy consumption, infrastructure and other aspects of the challenges are more and more, by 2030, the estimated global urban population ratio will reach 60%, urban energy consumption accounted for about 75% of the total global energy consumption, and lighting will account for nearly 40% of the city's total energy consumption. As an important part of Intelligent city, intelligent lighting has innate advantages in the number of Internet access points, and governments are actively advocating the construction and development of intelligent cities.

including Philips, Osram and other lighting giants have also laid the market, 2015 Philips Lighting in Los Angeles to participate in the Intelligent Road Lighting pilot project, the deployment of Philips Citytouch Intelligent Interconnection Road Lighting management system in Los Angeles, 2017 Philips Lighting will be the city touch The Flex Intelligent Interconnection Road illumination system is introduced into China and combined with the new generation of Internet of Things (Nb-iot) technology and the sky-wing cloud technology service, it can be used in all kinds of intelligent cities including urban emergency system, traffic signal management system, security monitoring system and so on to accelerate the construction of intelligent city in China

January 2018, Osram released a new intelligent City Central management platform Symphocitytm (a set of software and hardware in one of the Open platform system). In addition to the management of lighting, but also to the city security, environment, energy and communication integrated management of multi-functional integrated Intelligent City Central management platform. This will help city managers to improve efficiency, reduce costs and promote the development of smarter cities.

In addition, Chinese manufacturers Flying music audio, Chau Ming technology, etc. are also vigorously promote the wisdom of the street, the current major Chinese government-related projects, flying music audio now with more than 20 cities signed the Strategic Cooperation agreement of Intelligent City, and with Guizhou province Cengong County government to build the total investment scale of about 4 billion yuan "smart Cengong" project.

The continuous change of communication technology is the trend of diversification

Internet of things and intelligent lighting development to the present stage, the market has emerged Dali, ZigBee, Bluetooth, Wi-Fi, LoRa, Nb-iot, Sigfox, Z-wave, EnOcean and other communications technology.

In the field of indoor lighting, although there are many wireless communication protocols available, the Dali cable technology designed for Luminaires still occupies the highest market share. The system based on Dali protocol has distributed intelligent module, each module has the ability of digital control and digital communication, and the address and lighting scene information are stored in the memory of each Dali module. The Dali module realizes the functions of switching, dimming control and setting of the system by means of the Dali bus for digital Meta communication, transfer instruction and state information.

The system is more stable and reliable is the biggest advantage of the current wired control technology, but as the wireless technology matures, it will become the mainstream control technology in the future. The market share of the future Dali is expected to shrink gradually, while ZigBee and Bluetooth will occupy the main position, among them ZigBee is the most common wireless communication protocol of the lighting network. Because the development time is long, the technology is relatively mature, the ZigBee network structure itself has the superiority, moreover more saves the electricity. Taking the Chinese market as an example, more and more Chinese manufacturers are beginning to join the ZigBee Alliance, and the products have gradually shifted from the past to the domestic market for overseas export markets.

Outdoor lighting part, ZigBee at this stage is also the most widely used. However, due to the short application distance, there are many restrictions on outdoor lighting, it is expected that after 2017, ZigBee in the outdoor intelligent lighting market share will slowly decline.

With the rise of the Internet of things, many low power wide area networks (Lpwan) designed for low bandwidth, low power consumption, long distance, and large number of connected Internet applications have emerged. The Nb-iot of the authorized spectrum and the Lora (Long Range) and Sigfox of the unauthorized spectrum are the mainstream. Lpwan's long-distance communication capabilities can support large-scale networking deployments and avoid frequent battery replacement and maintenance costs.

In several low-power wide-area networks, Lora commercial early and more open, in 2015, the establishment of industrial alliances, at present, the most widely used in Lpwan. And in 2016 to achieve the standard frozen Nb-iot, due to the use of authorized spectrum, can avoid wireless interference, and have operator-level security and quality assurance, so in the higher reliability requirements of the intelligent lighting scene more competitive advantage, market share growth fastest.

Generally speaking, the market of all kinds of low-power wide area network is dispersed and the market share is still low. It is expected that with the development of technology and functional improvement, the market concentration will gradually increase.
